The Discoverer A/T3XLT is Cooper's On-Road All-Terrain tire designed for the drivers of pickup trucks, work vehicles and full-size SUVs who need a tire that provides the rugged durability required to keep up with their active lifestyles. Engineered to tackle dirt, gravel, mud and the urban jungle, the Discoverer A/T3XLT combines off-road prowess with agreeable on-road comfort and year-round traction, including in light snow.

Durable-Tread Technology combines a shred-resistant silica compound with the Discoverer A/T3XLT's next-generation all-terrain tread pattern. Cooper's Even Wear Arc Technology optimizes the shape of the footprint for balanced pressure at the contact patch, improving handling and promoting even treadwear. The tread pattern is designed to aid dry traction, while Whisper Grooves between the outboard tread blocks help reduce noise throughout the tire's life. Stone ejector ledges help prevent punctures due to stone drilling, and the Rugged Traction Shoulders feature alternating scoop and cleat lugs and biting edges designed for grip on rock, in thick mud or loose soil. Deep, circumferential channels and wide, lateral notches improve hydroplaning resistance, while multiple zigzag sipes in the independent tread blocks create the biting edges needed for traction in slippery conditions. Snow Groove Technology uses saw-tooth block edges to trap snow in the tread for effective snow-to-snow traction.

The internal construction of the Discoverer A/T3XLT consists of a robust, two-ply polyester casing. A single-ply, nylon reinforcement above two high-strength steel belts further increases durability and handling response, along with providing high-speed stability.

After one year and 8,000 miles the Toyo Extensa A/S II tires have performed really well with good wet/dry traction and a smooth ride. They are quiet and do ok with snow and ice. I would purchase them again. Special thanks to Tire Rack for outstanding service with fast shipping and good prices.

These are great tires and I have them on two vehicles now. I live in a snowy area and I feel these tires do a good enough job that I can avoid snow tires on front wheel/all wheel drive SUVs.
I would get these again for sure.

This is the first set of Toyo tires I have purchased. Being my truck has 15 inch wheels there is a
limited selection of tires available. So far, they are quiet and ride smooth. The quality of the tire
looks excellent. Tire Rack provided exceptional customer service with the purchase. They are
now my first choice when I want to purchase tires.

...For reference my tire size has 11/32 tread new. Both front tires were at 9.2/32 and Both rear tires were at 10.75/32. Going forward I will be rotating them every 6-7k but was happy to see such little wear on the rears...

I just did my first tire rotation at 9,990 miles today and measure my tread depths with a caliper. For reference my tire size has 11/32 tread new. Both front tires were at 9.2/32 and Both rear tires were at 10.75/32. Going forward I will be rotating them every 6-7k but was happy to see such little wear on the rears. I doubt they will last the 75k they have a tread warranty for but that'd be great if they do.

I only notice road noise from these when going 60mph+ and having to slightly turn the wheel through curves. It'll go from silent to a little noise until you straighten back out.

The tires have been great for my little car and have exceeded my expectations in the snow. After looking at the snow ratings and tread design I was ready to get a set of snow tires but gave it a few snow falls to test drive and I've felt so stable I didn't buy new tires or switch these.
